I’m rather new to Ruby and I’m trying to figure out how to print out  
percentage completed message on a single line instead of printing out  
massive amount of messages like the following:

Percentage completed: 1%,  
Percentage completed: 15%,  
Percentage completed: 50%,… so on…

It should just be one line.  
Percentage completed: ("#{percent\_completed\_variable}%")

Thank you…
